current tune and im happy with it for a start i will dial the trans and ve table more but need to solve this coming to a stop stall and random idle up while stoped in gear on the brake issue. ...

Lets give you a detailed setlist here.....

i purchased a 03 tahoe with 134k miles with transmission issues (no 2nd or 4th). trans was replaced with a rebuilt unit from a "reputable" local trans...

Ran so much better according to my butt dyno,(it is at 61% alcohol as i filled it with e85 fyi) it still wont kick down to idle when i left off the throttle. it seems to want to high idle when...

awesome ill give it a shot now! here is a datalog from a drive a few mins ago. it seemed ok then stalled again randomly.

throttle body is very clean, i have the ETB and it hasnt been touched physically or in the tune. i got the stall issue resolved but not it seems it has a hanging idle and wont coast.
ill do a log...

i assume it has to do with your ac pressure and ac disable speed

On my data log it has a chart for my old aem which was logged through the egr sensor. Since there is no wideband on this Tahoe nor egr the aem chart is pegged rich. That data is not being used and...

im going to try and pull some timing. but the fuel is set as it comes from factory on e85, with 91 it would run anywhere from 11.7-12.5 but stoich is 9.0 with e85 the truck wouldnt even run with 75%...
